NAME Invoke-DbaPfRelog



SYNOPSIS

Pipeline-compatible wrapper for the relog command which is available on modern Windows platforms.





SYNTAX

Invoke-DbaPfRelog [[-Path] <System.String[]>] [[-Destination] <String>] [[-Type] <String>] [-Append <Switch>]

[-AllowClobber <Switch>] [[-PerformanceCounter] <System.String[]>] [[-PerformanceCounterPath] <String>]

[[-Interval] <Int>] [[-BeginTime] <Datetime>] [[-EndTime] <Datetime>] [[-ConfigPath] <String>] [-Summary <Switch>]

[[-InputObject] <System.Object[]>] [-Multithread <Switch>] [-AllTime <Switch>] [-Raw <Switch>] [-EnableException

<Switch>] [<CommonParameters>]





DESCRIPTION

Pipeline-compatible wrapper for the relog command. Relog is useful for converting Windows Perfmon.



Extracts performance counters from performance counter logs into other formats,



such as text-TSV (for tab-delimited text), text-CSV (for comma-delimited text), binary-BIN, or SQL.



`relog "C:\\PerfLogs\\Admin\\System Correlation\\WORKSTATIONX_20180112-000001\\DataCollector01.blg" -o C:\\temp\\foo.csv

-f tsv`



If you find any input hangs, please send us the output so we can accommodate for it then use -Raw for an immediate

solution.





PARAMETERS

-AllowClobber [<Switch>]

If this switch is enabled, the destination file will be overwritten if it exists.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-AllTime [<Switch>]

If this switch is enabled and a datacollector or datacollectorset is passed in via the pipeline, collects all

logs, not just the latest.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Append [<Switch>]

If this switch is enabled, output will be appended to the specified file instead of overwriting. This option

does not apply to SQL format where the default is always to append.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-BeginTime [<Datetime>]

This is is Get-Date object and we format it for you.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-ConfigPath [<String>]

Specifies the pathname of the settings file that contains command-line parameters.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Destination [<String>]

Specifies the pathname of the output file or SQL database where the counters will be written. Defaults to the

same directory as the source.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-EnableException [<Switch>]

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.

This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables

advanced scripting.

Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own

try/catch.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-EndTime [<Datetime>]

Specifies end time for copying last record from the input file. This is is Get-Date object and we format it

for you.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-InputObject [<System.Object[]>]

Accepts the output of Get-DbaPfDataCollector and Get-DbaPfDataCollectorSet as input via the pipeline.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Interval [<Int>]

Specifies sample intervals in "n" records. Includes every nth data point in the relog file. Default is every

data point.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Multithread [<Switch>]

If this switch is enabled, processing will be done in parallel. This may speed up large batches or large files.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Path [<System.String[]>]

Specifies the pathname of an existing performance counter log or performance counter path. You can specify

multiple input files.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-PerformanceCounter [<System.String[]>]

Specifies the performance counter path to log.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-PerformanceCounterPath [<String>]

Specifies the pathname of the text file that lists the performance counters to be included in a relog file.

Use this option to list counter paths in an input file, one per line. Default setting is all counters in the

original log file are relogged.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Raw [<Switch>]

If this switch is enabled, the results of the DOS command instead of Get-ChildItem will be displayed. This

does not run in parallel.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Summary [<Switch>]

If this switch is enabled, the performance counters and time ranges of log files specified in the input file

will be displayed.



Required? false

Position? named

Default value

Accept pipeline input? False

Accept wildcard characters? false



-Type [<String>]

The output format. Defaults to tsv. Options include tsv, csv, bin, and sql.



For a SQL database, the output file specifies the DSN!counter_log. You can specify the database location by

using the ODBC manager to configure the DSN (Database System Name).

-------------------------- EXAMPLE 1 --------------------------



PS C:\\>Invoke-DbaPfRelog -Path C:\\temp\\perfmon.blg



Creates C:\\temp\\perfmon.tsv from C:\\temp\\perfmon.blg.

-------------------------- EXAMPLE 2 --------------------------



PS C:\\>Invoke-DbaPfRelog -Path C:\\temp\\perfmon.blg -Destination C:\\temp\\a\\b\\c



Creates the temp, a, and b directories if needed, then generates c.tsv (tab separated) from C:\\temp\\perfmon.blg.



Returns the newly created file as a file object.

-------------------------- EXAMPLE 3 --------------------------



PS C:\\>Get-DbaPfDataCollectorSet -ComputerName sql2016 | Get-DbaPfDataCollector | Invoke-DbaPfRelog -Destination

C:\\temp\\perf



Creates C:\\temp\\perf if needed, then generates computername-datacollectorname.tsv (tab separated) from the latest

logs of all data collector sets on sql2016. This destination format was chosen to avoid naming conflicts with

piped input.

-------------------------- EXAMPLE 4 --------------------------



PS C:\\>Invoke-DbaPfRelog -Path C:\\temp\\perfmon.blg -Destination C:\\temp\\a\\b\\c -Raw

Samples: 2227



The command completed successfully.

```



Creates the temp, a, and b directories if needed, then generates c.tsv (tab separated) from C:\\temp\\perfmon.blg

then outputs the raw results of the relog command.
